Daughter in the Material Science Phd progam at major state university with "world class" MS program. Vast majority of her peers are from abroad. Met some. All were the nicest, smartest folks you have ever met. I guess a benefit is that the probability of them leaving may help to increase the teamwork aspect in the program. But that is a guess. Great group of folks who hopefully might help change the world. Went to the recent Phd presentation where recent Phd graduates were honored. Let me tell you... hard to describe how inspiring these folks are. (MS is a pretty hard subject, with amazing applications. You may be thanking one guy who recently got his Phd should you ever get cancer.) Glad our universities welcome talent not demographics. HTH, RF.
